    Description

      Building a rule written in MVEL dialect like (*1) using BigDecimal_variable % Numeric_value operation (*1-1) in executable rule model, a compilation error (*2) occurs.

      (*1)

      package com.example.reproducer

import com.example.reproducer.Fact

dialect "mvel"

rule "rule1b"
    when
        $fact : Fact( $year : year, (($year % 400) == 0) || ((($year % 4) == 0) && (($year % 100) != 0)), $flag : "YES" )    // ..... (*1-1)
    then
        modify($fact) {
            leapYear = $flag
        }
        System.out.println("***** $fact: " + $fact + ", " + $year + " is a leap year? " + $fact.leapYear);
end

      (*2)

      [ERROR] /work2/testdir/reproducer_mc_1b/target/generated-sources/drools-model-compiler/main/java/com/example/reproducer/PF6/LambdaPredicateF6282A65CE56BF77478DD6D1D7E1AFE4.java:[17,133] bad operand types for binary operator '%'
  first type:  java.math.BigDecimal
  second type: int

          Bug - A problem that impairs or prevents the functions of the product. DROOLS-5959 BigDecimal_variable % Numeric_value operation causes a compilation error in executable model.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
